Outgroup f3-Statistics and Cladality Testing using f4-Statistics, Related to Figures 3 and 4
(A) Outgroup f3-statistics for the pre-Bronze Age to Early Bronze Age groups in the Eastern Steppe. We show top 15 outgroup f3-statistics of the form f3(Target, world-wide; Mbuti) out of 345 ancient and present-day populations for the six target groups: eastMongolia_preBA, centralMongolia_preBA, Fofonovo_EN, Afanasievo_Mongolia, Chemurchek_southAltai and Chemurchek_northAltai. Horizontal bars represent ± 1 standard error (SE) calculated by 5 cM block jackknifing.
(B) Testing cladality of the four ANA populations using f4-statistics. We show top and bottom 15 symmetric f4-statistics of the form f4(ANA1, ANA2; world-wide, Mbuti) out of 345 ancient and present-day populations for the four ANA-related target groups: eastMongolia_preBA, centralMongolia_preBA, Fofonovo_EN, DevilsCave_N. Horizontal bars represent ± 1 standard error (SE) calculated by 5 cM block jackknifing. f4-statistics with Z-score > 3 are highlighted in red.
(C) Testing cladality of Afanasievo and Chemurchek using f4-statistics. We show top and bottom 15 symmetric f4-statistics for the three target groups Afanasievo_Mongolia, Chemurchek_southAltai and Chemurchek_northAltai, in the form f4(Afanasievo_Mongolia, Afanasievo; world-wide, Mbuti), f4(Chemurchek_southAltai, Botai; world-wide, Mbuti), f4(Chemurchek _northAltai, Chemurchek_southAltai; world-wide, Mbuti), and f4(Chemurchek _northAltai, eastMongolia_preBA; world-wide, Mbuti) out of 345 ancient and present-day populations. Horizontal bars represent ± 1 standard error (SE) calculated by 5 cM block jackknifing. f4-statistics with Z-score > 3 are highlighted in red.
